The author tweeted “Cry, foe! Run amok! Fa awry! My wand won’t tolerate this nonsense”, sparking speculation she may be working on a new Harry Potter novel.
But many fans soon realised the author was talking about her upcoming Harry Potter spin-off film Fantastic Beasts and Where to Find Them.
Dedicated fans on Reddit soon discovered that the words “New York” and “Newt Scamander” were hidden as anagrams in the post.

A fan called Emily Strong later solved the puzzle, tweeting JK Rowling to say: “Newt Scamander only meant to stay in New York for a few hours…#anagram.”
Newt Scamander is the writer of JK Rowling’s 2001 book Fantastic Beats and Where to Find Them, a copy of Harry Potter's textbook of the same name mentioned in Harry Potter and the Philosopher's Stone.
